Evaluation of Integrated Weed Management Technologies for the Control Annual Grasses and Broad Leaf Weeds in Wheat Fields of the Hadiya Zones of Southern Ethiopia

Weeds are a major pest of wheat production Ethiopia. It accounts yield loss above 36.3% in wheat due to uncontrolled weed growth. Field experiment was conducted to evaluate the efficacy of herbicides and cultural practices viz, palas, topic, hand weeding and weedy cheek were tested at Haqumura site in a Randomized Complete Block Design (RCBD) with four replications during 2018 and 2019. Except plant height all parameters like spike length, number of tiller per plant, biomass yield, number of seed per spike, 1000 seed weight, and seed weight per plot were significantly affected by the treatments. Especially those yield and yield components that are treated with agro chemical called Pallas 45 OD showed significant difference in all cases except plant height that is not significantly difference in all treatments. So in nutshell application of Pallas 45 OD according to company recommendation 30-35 days after weed emergence is the best agro chemical for the control of weed in wheat fields for our regions and other similar agro ecology especially for the control of wild oat in wheat fields next to hand weeding.
